Attitudes of blood and plasma donors towards biobanking for longitudinal health research.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBlood and plasma donations provide a unique opportunity for setting up a biobank. Remainders of donations can be stored together with questionnaire data to allow for longitudinal health research. Insight in the attitude and understanding of potential concerns of donors towards biobanking allows incorporating their perspective in the set-up of biobanks as such.
methodsIn an online survey in July/August 2021 among 409 Dutch donors, we asked about their attitudes towards the collection and storage of remainders of donations, questionnaires, and DNA, and towards the storage period, data sharing and linkage, and feeding back results and outcomes.
resultsThe overall attitude of participating donors towards biobanking remainders of donations is very positive with 99% indicating willingness to provide their consent and 94% to fill out questionnaires. Most respondents (74%, n = 292/395) would agree to a long-term storage of 30 years. When asked about potential concerns, respondents mostly mentioned personal data security (30%), commercial use of data (11%) and misuse of data (5%). Also, 40% (n = 155/390) showed some hesitance towards the storage of DNA, including 28% (n = 111/390) who would give conditional consent if being informed on for instance DNA utilisation. Finally, the majority would like to receive feedback of research results, and indicated this to contribute to a greater likelihood of biobank participation.
conclusionOur findings show high support among surveyed donors for the storage of donation remainders in a biobank, provided high data security standards and clear communication about data protection measures and usage of biobank data and materials.
